Description
Die vorliegende Erfindung betrifft einen Brennstoffmischer für eine Brennstoffzelle, insbesondere einen Brennstoffmischer für eine Brennstoffzelle, in dem sich bei einer elektrochemischen Reaktion entstandenes Wasser zurückgewinnen läßt.The The present invention relates to a fuel mixer for a fuel cell, in particular a fuel mixer for a fuel cell, in the water formed in an electrochemical reaction win back leaves.
Brennstoffzellen wandeln in Brennstoff und einem Oxidationsmittel gespeicherte chemische Energie in einer chemischen Reaktion an Elektroden in elektrische Energie um. Brennstoffzellen werden in vielen Varianten hergestellt, die sich nach unterschiedlichen Kriterien ordnen lassen. Je nach verwendetem Elektrolyt gibt es fünf Typen: Brennstoffzellen mit basischem Elektrolyt, mit Phosphorsäure, protonaustauschenden Membranen, Schmelzkarbonat und Feststoffoxiden. Unter diesen schließen Brennstoffzellen mit protonaustauschenden Membranen sogenannte Direktmethanol-Brennstoffzellen ein, in denen Methanol direkt, ohne vorherige Umwandlung in Wasserstoff als Brennstoff eingesetzt wird. Letzterer Typ von Brennstoffzellen ist Gegenstand aktueller Forschung und findet Anwendung in großen Aggregaten sowie mobilen Generatoren, etwa in Kraftfahrzeugen.fuel cells convert into fuel and an oxidant stored chemical Energy in a chemical reaction to electrodes in electrical Energy around. Fuel cells are produced in many variants, which can be arranged according to different criteria. Depending on there are five electrolytes used Types: fuel cells with basic electrolyte, with phosphoric acid, proton-exchanging Membranes, molten carbonate and solid oxides. Among these include fuel cells with proton-exchanging membranes so-called direct methanol fuel cells, in which methanol directly, without prior conversion to hydrogen is used as fuel. The latter type of fuel cell is the subject of current research and is used in large aggregates as well as mobile generators, such as in motor vehicles.
Die Technik von Brennstoffzellen stellt derzeit viele Herausforderungen. Brennstoffversorgungssysteme sind der Gegenstand aktueller Forschung, darunter die Rückgewinnung von bei einer elektrochemischen Reaktion entstandenem Wasser sowie eine Minimierung von Bauvolumina.The Technology of fuel cells currently presents many challenges. Fuel supply systems are the subject of current research, including the recovery of water formed in an electrochemical reaction as well a minimization of construction volumes.
Die wesentliche Aufgabe der vorliegenden Erfindung besteht darin, einen Brennstoffmischer für eine Brennstoffzelle zu schaffen, in dem sich bei einer elektrochemischen Reaktion entstandenes Wasser rückgewinnen läßt.The essential object of the present invention is a Fuel mixer for one To create a fuel cell in which an electrochemical Recover the reaction of produced water leaves.
Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, einen Brennstoffmischer für eine Brennstoffzelle zu schaffen, in dem Kondensor und Mischspeicher in einen Körper integriert sind, so daß ein geringes Volumen beansprucht wird.A Another object of the present invention is to provide a Fuel mixer for to create a fuel cell, in the condenser and mixing tank in a body are integrated so that a low volume is claimed.
Um diese Aufgabe zu erfüllem, weist die vorliegende Erfindung auf ein Gehäuse mit einem ersten Innenraum und einem zweiten Innenraum, der sich unmittelbar an den ersten Innenraum anschließt, wobei wenigstens ein Lufteinlaß und wenigstens ein Wasserauslaß den ersten Innenraum und den zweiten Innenraum verbinden, wenigstens einen Radiator, der im ersten Innenraum montiert ist, und eine gasdurchlässige Membran, die auf dem Lufteinlaß angebracht ist.Around to fulfill this task, The present invention relates to a housing having a first interior space and a second interior, which is directly adjacent to the first one Interior connects, wherein at least one air inlet and at least one water outlet the connect the first interior and the second interior, at least a radiator mounted in the first interior, and a gas-permeable membrane, which is mounted on the air intake is.
